Qt 5.4 Adding VideoFile to project

Hi, sorry for newbie question...how Can I add the video file to a project?? I tried to add it to .src file but doesnt not work (Size probably...). I need a path to /video.mp4 in a project folder, but not absoluteFilePath. Or what is the proper way to include a video file to a project. I'd like to send my app with the videofile to someone.
Thanks for help.
